Pada tulisan sebelumnya kita telah melakukan obtain citra landsat Level 1 GeTIFF Product, dimana file citra pada jenis produk ini merupakan file landsat yang masih terpisah layernya menurut band masing-masing. Dengan demikian kita harus melakukan proses komposit sehingga menjadi sebuah citra yang dapat digunakan untuk analisis atau interpretasi.
Thematic Mapper (TM) was a excessive-decision scanner on Landsat satellites (Landsat four and 5). It collected photographs in visible, near infrared, mid infrared and thermal bands with a spatial decision of 30 meters. Landsat 6 dirancang untuk melanjutkan program Landsat. Satelit ini diluncurkan pada 5 Oktober 1993 menggunakan Titan II tapi gagal mencapai orbit karena masalah teknis. Sebagai akibatnya, Landsat four dan Landsat 5 digunakan lagi (melebihi umur yang telah ditetapkan). Namun hanya Landsat 5 yang masih beroperasi.
The WELD products can be found for the conterminous United States (CONUS) and Alaska as weekly, monthly, seasonal (three month) and annual merchandise. Sedangkan untuk band eight atau sering disebut band pankromatik memilki resolusi spasial 15m. Citra Landsat yang digunakan dalam penelitian ini adalah citra Landsat ortho 14,25m dimana sudah digabungkan antara multispektral dengan pankromatiknya serta kombinasi band yang digunakan hanya band 7, four dan 2. Moreover, the whole Sentinel idea envisages paired operation, meaning a second satellite, Sentinel-2b, will comply with its sister into orbit in 2016.
Observe how vegetation really pops in pink, with more healthy vegetation being more vibrant. It is also easier to tell various kinds of vegetation aside than it is with a pure shade picture. This is a very commonly used band combination in remote sensing when taking a look at vegetation, crops and wetlands. SCP allows for the calculation of a classification report with the share and the world of land cowl classes. TIRS bands are acquired at 100 meter resolution, however are resampled to 30 meter in delivered data product.
The 30-meter decision of Landsat scenes is ideal for portraying a view of this and other cities as they develop and alter. Landsat’s forty-12 months-long report can be utilized like a time machine, permitting viewers to jump again years or even a long time to check one period of a metropolis’s life to another. This band combination is much like the 5, 6, 4 band combination shown above, but vegetation exhibits up in additional vibrant shades of green. This band mixture was used for the worldwide Landsat mosaic created by NASA.
